Abstract
A method and system of extracting a perceptual feature set for image/video segmentation are disclosed. An input image is converted to obtain a hue component and a saturation component, where the hue component is quantized into a number of quantum values. After weighting the quantized hue component with the saturation component, the weighted quantized hue component and the saturation component are subjected to a statistical operation in order to extract feature vectors. Accordingly, the method and system provide overall segmentation results that are very close to human interpretation.
Claims16
A method of extracting a perceptual feature set, comprising using a processor to perform the steps of:
- converting an input image to obtain a hue component and a saturation component;
- quantizing the hue component into a plurality of quantum values;
- weighting the quantized hue component with the saturation component;
- and
- subjecting the weighted quantized hue component and the saturation component to a statistical operation in order to extract feature vectors.
A system for extracting a perceptual feature set, comprising:
- a conversion unit configured to convert an input image to obtain a hue component and a saturation component;
